NAME

       ipmctl-delete-pcd - Clears select partition data from the PCD

SYNOPSIS

           ipmctl delete [OPTIONS] -pcd [TARGETS]

DESCRIPTION

       When Config is specified, the Current, Input, and Output Data Size and Start Offset values
       in the Configuration header are set to zero, making those tables invalid.

           Note
           When Config is specified, only PCD partition 1 is modified. If the platform is
           rebooted prior to creating a new goal on any targeted PMem modules, UEFI platform
           firmware will detect the missing tables and, if possible, restore previous config
           using the PCD partition 0 tables.

           Note
           This action can be useful when moving PMem modules from one system to another, as goal
           creation rules may restrict provisioning PMem modules with an existing configuration.
           Deleting the PCD can be used as a way to prepare a PMem module for provisioning with
           the create -goal or load -goal commands by clearing existing configuration metadata.
           This allows the PMem module to be provisioned in isolation using the create-goal
           command with the -dimm option. Once the PCD has been deleted the desired goal should
           be created before rebooting.

           Warning
           This command may result in data loss. Data should be backed up to other storage before
           executing this command. Because of data dependencies, other commands may be affected
           until the system has been rebooted.

OPTIONS

       -f, -force
           Deleting the PCD data is a destructive operation which requires confirmation from the
           user for each PMem module. This option suppresses the confirmation.

       -h, -help
           Displays help for the command.

       -ddrt
           Used to specify DDRT as the desired transport protocol for the current invocation of
           ipmctl.

       -smbus
           Used to specify SMBUS as the desired transport protocol for the current invocation of
           ipmctl.

           Note
           The -ddrt and -smbus options are mutually exclusive and may not be used together.

       -lpmb
           Used to specify large transport payload size for the current invocation of ipmctl.

       -spmb
           Used to specify small transport payload size for the current invocation of ipmctl.

           Note
           The -lpmb and -spmb options are mutually exclusive and may not be used together.

       -o (text|nvmxml), -output (text|nvmxml)
           Changes the output format. One of: "text" (default) or "nvmxml".

TARGETS

       -dimm [DimmIDs]
           Deletes the PCD data on specific PMem modules by supplying one or more comma separated
           PMem module identifiers. The default is to delete the PCD data for all manageable PMem
           modules.

       -pcd [Config]
           Clears the configuration management information.

EXAMPLES

       Clears the Cin, Cout, Ccur tables from all manageable PMem modules

           delete -dimm -pcd Config

LIMITATIONS

       The specified PMem modules must be manageable by the host software, and if data-at-rest
       security is enabled, the PMem modules must be unlocked. Any existing namespaces associated
       with the requested PMem modules should be deleted before running this command.

RETURN DATA

       For each PMem module, the CLI will indicate the status of the operation. If a failure
       occurs when deleting the platform configuration data from multiple PMem modules, the
       process will continue deleting the remaining PMem modules.
